WINDING Application filed July 14,

10 all whom t may concern Be it known that Anoniexnn D. Soo'r'r, deceased, late a citizen ot the United States, residing at Jersey City, in the county of Hudson and State ot New Jersey, invented certain new and usetul Improvements in lviudiug Machines, of `vhich the :following a '.tull, clear, and exact description.

This invention relates to n'iachines tor winding strands ot material such as `Wire, thread, or ribbon into coils, helices or bob bins, and has particular ret'erence to a machine `tor Winding copper Wire into electric coils or helices for use in various types ot electrical apparatus. The particular invention herein described is in the nature ot an improvement upon the machines described in United States Patents #654,588 issued rluly 31st, i900, #798,864 issued September 5th, 1905, and :#1,344,432 issued June 22nd, 1920. The invention directed to an improvement upon the turret control and operation disclosed in the last inentioued U. S. patent. n the patented inachines a plurality ot coils are Wound simultaneously in separate zones upon a single spindle or inandril, the convolutions ot Wire boing Wound in layers superimposed one upon the other. lViren the required nurnber of layers are completed the machine stops and all of the coils on the spindle are removed in a body or stick and afterwards separated into individual coils. After` the removal ot the stick, the spindle is prepared 'tor another winding operation by placing thereon a paper or other suitable tube, tastening thereto at the proper points the vag rions strands oit Wire, and then starting up the machine. The operation ot preparing the spindle and manipulating the linislied coils consumes considerable time during which the machine in accordance with the earlier inventions was idle, which resulted in a limitation of the output ot the n'iachine. In the U. S. Patent #15M-,432, the intervals oi idleness were reduced in duration by the provision ot a` plurality ot spindles carried by a turret and adapted to be rotated successively into Winding positions, and suitable driving connections were made to each spindle when in the Winding position.

An object of the invention is to improve and simplify the turret controlling and operating mechanism. in order that the neces- MACHNE.

sary steps between the winding operations may be more easily and rapidly carried out and by relatively unskilled labor. @ther objects and advantages will be apparentl troni the I'ollowing description ot an einbodiment ot' the invention, and the novel features will be particularly pointed out hereinafter in claims.

In the accompanyingl drawing.:

Fig. 2 is a plan ot the same;

Fig. 3 is a front elevation ot the turret and its operating mechanism;

Fig. 4 is an end elevation ci the saine;

Fig. 6 is a section through the saine taken substantially along the line 6 6 ot Fig. 4l.

ln the illustrated embodiment ot' the invention, a bearing, housing l, which is supported upon a machine trame 2, rotatably supports a driving spindle 3. The spindle 3 is rotatably driven in a suitable manner such as by a belt t aassing over a pulley 5 there on, the belt 4t being driven from a pulley G which may have a driving connection troni a suitable source of power (not shown) and the application of Which to the pulley 0 is controlled by a shaft 7.

A turret 8 mounts a plurality ot spindles 9 and l0 for rotation about their axes and for bodily rotation about the axis ot the turA ret. The spindles are mounted in the turret so as to be slightly divergent from one an* other and trom the axis ot' the turret and are bodily rotated about the axis of the turret by a gear l1. The axis ot' the turret 8 is slightly oblique to the axis ot the spindle 8 so that when the gear 1l is rotated to bodily rotaie the Winding spindles 9 and l0, the latter will be carried successively into aligned positions relatively to the driving spindle 3, which aligned positions will be hereinafter referred to as the Windino' positions because in these positions the spindles Will be rotated about their own axes for the Winding thereon ot the Wire.

The driving spindle 8 is provided, at the end adjoining the Winding spindles, with a chuck l2, and Ithe spindle 3, Which is slidable as Well as rotatable in the housing l, may

be shifted cndwisc to carry the chuck 12 into or out of chucling engagement with the free end of the aligned winding spindles. When. the chuck engages with the winding spindle a driving connection is effected between the driving spindle 3 and the winding spindle, and this connection is broken by shifting the driving spindle 3 endwise in a direction to carry the chuck 12 out of engagement with the spindle.

A rod 13 is disposed parallel with the driving spindle 37 and is mounted for endwise sliding movement in bearings 14 which are mounted upon the machine frame 2. The rod 13 is provided with a follower block 15 carrying a follower pin 16 that runs in a cam groove 17. The cam groove 17 extends periphcrally of a cylinder 18 which is rotatably mounted upon the machine frame 2 and driven by a gear 19 and gear train 2O from any suitable source of power, preferably from a shaft 21 (Figure 1) which has a worm driven connection with the spindle 3. '.lhus during the rotation of the driving spindle 3 the drum 13 will be rotated, and the cam groove 17 will act through the follower pin 13 to reciprocate the rod 13. The iod 13 .is provided with suitable wire or thread guides 22 which are adapted to guide the wire or thread to be wound from suitable spools or bobbins (not shown) to the winding spindle upon which the coils are being wound. Any number of guides 22- may be mounted upon the rod 13 and it will be understood that these guides will be spaced to correspond with the spacing of the coils.

A pinion 23 meshing with the gear 11 of the turret is provided with a tubular hub 24 which extends within and is rotatably supported in a bearing of the machine frame 2. screw pin 2G extending through the bearing 25 and from the inner bearing surface thereof runs in an annular groove 27 of the huh 24 of the pinion 3. An operating shaft 23 is slidaloly and rotatably mounted in the pinion and its huh. A clutch element 29 is secured by a pin 30 upon one end of the shaft 23, and upon the 'face abuttingl the pinion 23 is provided with clutch teeth 31 which may be shifted into and out of clutching engagement v'with eomlilementary clutch teeth 32 that are provided upon the abutting face of the pinion 23. The movement of the clutch 29 into and out of clutching engagement with the pinion 23 is accomplished b v shifting the shaft 23 entlwise of itself.

The shaft 23 is also provided with a pinion 33 which meshes with a gear 34 fixed upon a control shaft- 35. The shaft 35 is rotatably mounted in suitable bearings 3G of the machine frame 2` and extends across the front of the machine. The control shaft at its end adjacent the driving spindle 3.

carries a cylindrical cam 37 having in its peripheral surface a cam groove 33. A lever 39 is pivotally mounted at 40 upon a suitable bearing of the machine frame 2 and at one end has a followerl pin running in the cam groove 33, whereby the lever will be oscillated in accordance with the character of the cam groove. The lever also has a forked end 41 which embraces the driving spindle 3, and by engagement against a collar 42 on the spindle 3 may operate the spindie in an endwise direction when the shaft is rotated. It will be-understood that a suitable spring (not shown) is provided within the housing 1 for normally stressing the driving spindle 3 in a direction opposite to that to which it is shifted by the lever 39.

A suitable operating handle 43 is secured upon the shaft 23, and assuming that the shaft 23 is in such a position that it is unclutched from the pinion 23, the rotation of the shaft 23 by the handle 43 will effect a driving of the shaft and an endwisc movement of the driving spindle 3. lVhen the handle 43 is operated to shift the shaft 23 into clutching engagement with the pinion 23, a rotation of the shaft 23 by the handle will not only rotate the shaft 35 but also the turret gear 11 and through it effect a bodily rotary movement of the winding spindles 9 and 10.

A disc 44 is secured upon the end of the shaft 35, adjacent the operating handle 43, and has in its periphery two track ways 45 and 46. The trackway 45 extends about 22 O around the disc and at .its ends communicates through gateways 47 with the ends of the trackway 46. The handle 43 is provided with a collar 43 which is adapted to extend into one or the other of thc trackways 45 or 4G, and by engagement with the ends of the traclrwayslimit the rotation of the shaft 35 which in turn limits the rotation of the operating handle 43. lWhen the collar 43 is at either end of the traclway 45 it may be shifted endwise of one of the gateways 47 into the traclway 43. or vice versa. The shaft :.3 can therefore only be shifted endwise when the collar 4S can be shifted through one of the gateafays 47. At all other times the collar 43 will be locked against endwise movement. and through it the shaft 23 will be locked against endwisc movement.

The pinion is provided with a plurality of apertures 49 extending from face to face and arranged in a circular row concentric with the axis of rotation of the shaft A locking pin 50 is disposed parallel with the shaft 23 and mounted for endwise sliding movement in the bearing 25. The locking pin 50 is disposed at such a distance from the axis of the shaft 23 that when shifted endwise it may enter any of the apertures 47 which are brought inte alignrnent theren'fith through the rotation oli the pinion 23. The collar 118 overl'ie's one end oit the locking' pin 5() and is eidepted to engage it ond shift it end-Wise into one oit the npi-rtures 44T of the pinion 23' to lock the letter gelost rotation when: Vtl-'ie slnit't 2i" is shifted ei'rdwisein it direction to uncluteh it from the pinion it plnrarlity of ejector pins extend r'orn the clutch element 29 toward the abutting liiee of the pinion 23, irn'd these ejector pins aire lr-ranged in :i circular rou' concentric with the :ixis of the shaft 2S, so that When the clutch .lneniher 222) is carried into clutchingr engagement With the pinion 23, the ejector pins `will enter thenpertui'es i9 oit the pinion ond ejiect the locking` pin 5G tliei'et'rotn.

A spring` linger o2, provided upon the han dl'e ft?) is Iadapted vto click over i` pin 53 yn'ovided upon the end time ot the' disc -iilund `by the sound and drug created indica-ite when the col-lar f1.8 is approximately midway hetiveen the ends of the trncle wey rhe shaft 7, Which controls the activity ot' the driving spindle is provided with sin operating handle 54e having n tongue 55 extendingil beneathv the shaft and adapted to enter u notch (not shown) in the peripheryV et e collar 56 which ie fixed upon the shaft 85. The position ot the slot in the coller 56 is stitch that the tongue 55 can only1 enter it when one ot the Winding' spindles is in alignment with the driving;` spindle t3 find clutched thereto. It Willi there- 'tore` he impossible to stort the machine unless n windingr spindle is proper-ly positioned and clutched to the driving spindle. Also it will he impossible to operate the turret or to declntch the Winding spindle und drivingr spindle while the machine in operation.

ln the operation ot this device, the paper tiihes or other tornis upon which the coils :ire to he Wound are slid over the 'tree end ot' the disengaged windingl spindle and secured thereon :in any suitable mennen The threads or vWires to he Wound are conducted over the guides 22 and secured to the forros in :uit suitiihle manner. The turret is opcrnted to place the spindle with the vtorni iii filignnfient with the driving spindle :ind clutch the lutter thereto. Then this is :1ci'fotnplished the shat't will he in such u position that the starting sind stopping hnidle en he lniinipuhited to start the mechine` The coils will then 'he Wound nutonni-ticiilly, and when they are completed the machine will he stopped either manually or hy the automatic mechanism disclosed in the prior patents hereinbefore referred to. During' the Winding operation, the operator will place :i new 'term upon the unused spindle. i

The operator, at the completion oi the winding movement, operates the handle d3 h y rotating it until the coll-nr 48 is reached hy one end oit the traclrwzi-y 45. During,` this rotation ot tl'ie handle1 the she-itt 35 will he rotated, hut the pinion will not he rota-ted since it is unclutched tronil the shnt't 28. 'this increment of rotation ot the shtttt will canse the coni 37 thereon to opernte the lever 3) and drew the drivingv spindle and its clinic-hr '2 out oit en giigcinent with the Winding' spindle which is then in ulignuuint therewith. The handle t3 is then oiiierzrte'd to pnll the slinift 2S endnise and ciu-ry 'he clutch inenrher 2S) into clutching enejog'eineut with the pinion 2?), the movement ot the coller 4:8 through the gateway 4'! permitting this cndWis-e nnievenient oft the shzfitt During;I this endwise movement the ejector pins 5l Will enter the apertures in the pinion 9,3 and eject theretroin the loekinp' pin 50.

it the cinnpietion ot' this en'dwi'se nierenient oi the shaft 28, the coller #i8 will lie in the trackwuy d6, and then further rotetion ot the handle 4i?) in the sinne direction een he ettected. During continued rotation ot the hzindlen the pinion 23 will he driven and will in turn drive the turret geur ll. :and rotate the Winding spindles bodily about the :iris oi. they turret to carry e new Winding sinn'dle into alignment with the driving spindle This increment ot nieveinent will Vhe limited hy the engagement of the opposite end of the track 45 With the collar 48.

During thisI last. mentioned increment ot rotation, the shaft will rotate, hut the com groove will have such n direction that (iluring this portion ot its revolution it will not` atleet the position ot the lever 59. The handle -l-l may then he oiiereted to shit't the shntt 2b eudu'ise und corri' the Coller i8 to the other g'zitenuei' t? into the trzicliwny During this endu'iso movement ot the shnlt the clutch uieinhcr 2) will he disengaged troni the pinion 23, and the coller will engage and operate the locking; pin 50 in a direction to cause it to enter one o't the apertures fl-V9 of the pinion 23, the ejector pins being withdrawn during the seine movement. rllhe looking' pin then prevents :rotation ot the pinion *2S and thrintgh it rotation ol the turret.

The lnindle -il-3 may now he rota ted tnt-ther in the suine direction. and during this rotation the turret will not he operated hut the shaft 35 will he rotated. This increinent oi rotation of the shaft 35 will operate the lever 39 to relee se the driving spindle 3 and permit the spi-iner within the housing' (not shown) to carry the driving spindle into chuclrinrj engagement with the Winding; spindle which has just been brought into alignment therewith. This last posit-ion .is

lil() lil) reached when the collar 4S is approximately midway between the ends of the trackway and will be indicated by the clicking engagement of the spring 52 with the pin 53. The locking pin prevents movement of the turret to displace the spindles while the driving spindle is being engaged with the spindle or disengaged therefrom. rIhe threads or wires are next disconnected from the coils which have been wound and connected to the new form upon the spindle now in driving position, whereupon the lever 54 may be operated to start the machine.

lf'hile a new set of coils is being wound the operator wili remove the previously wound coils and place a new form upon the free spindle. `When the machine again stops at the completion of a new set of coils the operator will rotate the handle 43 in the same direction until the end of the trackway 45 engages the collar 4S. This operates the shaft 35 to carry the chuck 12 out of engagement with the active winding spindle. The shaft Q8 may then be shifted endwise to clutch the member 29 with the pinion 23, during which clutching movement the ejector pins 51 will enter the apertures 49 and push the locking pin 50 out of locking engagement with the pinion. The handle 43 is then operated to carry a new spindle into winding position as before explained.

It will be obvious that various changes in the details and arrangements of parts herein described and illustrated for the purpose of explaining the nature of the invention, may be made by those skilled in the art within the principle and scope of the invention as expressed in the appended claims.
